A key project in the renovation of resale homes is the refurbishment of doors and windows—after all, "doors and windows are the eyes of your home." Whether this renovation is done properly can significantly impact the overall aesthetic appeal of your living space down the road. Today, we’ll walk you through common pitfalls to watch out for during door and window renovation—and share some practical solutions to help you avoid them.
Doors and windows don't need to be replaced.
Common misconceptions:
The doors and windows are still new—they don’t need replacing, which can save you from unnecessary expenses. However, potential issues with doors and windows aren’t always easy to spot with the naked eye. That’s why we still recommend replacing them during your renovation project.
Response method:
When renovating, it’s best to replace the doors and windows first—before proceeding with the next steps—since removing the existing windows can damage both interior and exterior walls. Homeowners should clearly decide which brand of profiles to use, as the quality of these profiles will directly influence the overall grade, sealing performance, and durability of the doors and windows. Don’t let yourself be misled by the vague marketing claims about “affordable PVC doors and windows” in the market.
Additionally, when making your purchase, be sure to head to a reputable building materials market. Street-side stalls often have rudimentary processing equipment, making it impossible to guarantee the precision and strength of their products. This is especially true for PVC windows and doors—many vendors there use low-quality or even completely absent steel reinforcements in their frames, and their other components are also subpar.
Wood door renovation only requires varnish.
Common misconceptions:
Wooden door deterioration is also a prominent issue in the resale housing market. However, if the material is sturdy and you happen to love the design, a simple repaint usually suffices to give them a fresh, new look. That said, if any of the following problems arise—such as peeling or warping—the wood itself has likely undergone structural changes, making it essential to replace the doors entirely. Keep in mind, though, that renovating wooden doors isn’t as straightforward as just applying clear coat; other techniques may be required depending on the extent of damage.
Response method:
Since any base and material can be refinished, however, if the original finish was clear oil with a darker hue, applying a lighter-colored varnish won’t fully cover it—unless you first use an even darker shade to conceal the original color. On the other hand, if the surface was originally finished with a mixed oil, there are no color restrictions; you can freely choose any shade you like for the new finish.
If the wooden door surface is damaged—say, with cracks or dents in certain areas—you should first fill the damaged spots with putty, then sand it smooth with sandpaper, and finally apply a primer followed by the topcoat. If the underlying surface remains intact, you can simply proceed to paint directly.
